Development slowed down a bit in the past couple of months, but still a number of (important) changes have been made:
* added bossfights;
* added CHASE cell (the UFOs chase the spaceship for 5 seconds);
* moved HUD icons column to the left side;
* touched up graphics;
* made various improvements/fixes;
* extended/improved manual.

* the final boss graphics will be totally different;
* the background graphics might change as well;
* there are 47 kB of floppy disk space and 140 kB of RAM left: they will be used to make improvements and/or to add new features.
